Therefore all men should marry and be married, and since through the fall of our first parents we have been so spoiled that we are not all fit for marriage, yet those who are not fit for the married state should so live that they walk chastely and honorably and give offense to no one, though at the beginning it was not so and all were fit to become married. But now it happens that some do not want to enter the state of matrimony even though they are fit and qualified to marriage. Some, on the other hand, would like to be married and are unable to do so. Neither do I condemn and disapprove of these. The third group, however, who desire and want to be married and are also fit and competent to do so, even though they enter the marriage state contrary to human laws, do what is right, and nobody should be scandalized by what they do. For the married state should not be forbidden to anyone who is competent to be married, but should be free and open to everyone. And this estate should not be condemned and rejected as something foul and unclean, as the pope and his followers do. For to be married is an ordinance and institution of God, since when God created man and woman, he himself placed them in this estate in which they not only could but should live godly, honorable, pure, and chaste lives, bearing children and peopling the world, indeed, the kingdom of God.
Who, then, would be so bold as to tear down the glorious, holy ordinance of God or to say anything against it? Who, then, is so bold as to condemn this ordinance and despise it as useless, unholy, and unnecessary? (“Sermon at Marriage of Sigismund von Luindenau, 1545” (Luther’s Works, v. 51, p.359)
